About working with Indicators
In this blog, I will show you how easy it is to define and use a color indicator in Dragon1 so you can focus on the things that matter.
Do you recognize the following: You are presented with a list of, for example, 100 software applications; only five are worth looking at in detail because they are problematic. Only the thing is, all the applications in the list are presented in the same way: the same colors, font type, etc..
The five important ones to look at are like needles in a haystack. If you don't know where to find these five applications in the list, you might not notice them or overlook them. They don't stand out from the rest.
How great would it be if you could give certain items, in this case, the applications, in a list a different color than the others, so they stand out and you can quickly focus on them! In Dragon1, that can be done with Indicators.
What is an Indicator?
An indicator is an entity or an object that provides specific information on the state or condition of something.
In the Dragon1 Architecture Repository, you can define indicators that will change the color of cells in a table depending on the value of an attribute. You can do or change many other things with an indicator, but we focus on the color indicator in this blog.
For an indicator to work, you need to enter a minimal set of things: the name, the event, the condition, the action, and the context. Together, these five things form a rule.
Suppose in your list that a software application has a maintenance cost of more than 50.000 USD per year. That is too costly for your organization, and this application should be replaced with a cheaper one. In that case, you want the value (maintenance cost) too high to be shown in red. For that, you would need to define an indicator.
An example list of software applications
Below is an example list of software applications in the architecture repository we imported from an Excel sheet (.xls) file.
In Dragon1, your data is stored (logically) in the database in cabinets, dossiers, and folders. You can define and rename as many cabinets, with as many dossiers and folders as you like.
In this example, the user has added user-defined fields like issues, maintenance cost, service contracts, and available versus used licenses.
As you see, the applications look the same, and there is nothing that attracts your attention.
Now, we will define a color indicator for maintenance cost.
Defining an Indicator
We can define an indicator by choosing Insert Archifact > Indicator on the application menu. See the screenshot below for an example:
After clicking, a dialog appears, and in the dialog, you can fill in the identification information on the first tab and the rule information (an event, condition, and action) on the behavior tab.
Here you see a screenshot with the second tab of the dialog that is filled with information: the event, the condition, and the action:
- Rule Event: onload
- Rule Condition: software.maintenance-cost > 50000
- Rule Action :tablecell.background-color = red
More Events, Conditions, and Actions you can use can be found on the Dragon1 Help.
You can give an indicator a certain scope: a cabinet, a dossier, a folder, a model, or an entity class (like software or visualization). In this example, we did not set the context, so it automatically only works in the folder where you have placed it.
The next time you click a folder in this cabinet and if it contains software applications, the indicator in that folder is running on that data. Below, you will see the result.
Immediately, it will draw your attention, and you will be focused on dealing with that signal!
Summary
In this blog, I have shown you how you can make use of a color indicator in the Dragon1 Architecture Repository.
I have shown you how easy it is to create a minimal indicator. Working with indicators like this (for example, IT Asset management) saves money and makes you focus on spending time only on the essential things.
